IMPROVEMENT IN FASTENERS F'OR THE MEETING'RAlLS OF SASHES.

Specification forming part of Letters Patent No. 187,316, dated February 13, 1877; application iiled September 11, 1876.

To all whom it may concern Be it known that I, DAVID S. ROBERTS, of Boston, ofthe county of Suffolk and State of Massachusetts, have invented a new and useful ,or Improved Sash Fastening; and do hereby declare the same to be fully described in the following specication, and represented in the accompanying drawings, of which- Figure 1 is a top view, Fig. 2 a side elevation, and Fig. 3 a longitudinal section, and Fig. 4 is a horizontal sect-ion, of it as it ap pears with the catch or swinging lever locked. Fig. 5 is a top view of it with the catch or lever thrown back or unlocked. Fig. 6 is a front elevation ofthe front catch-plate, show ing its locking-notch.

' sashes, V S L S. The rearniost of the said plates B is provided at its front with a curved projection, a, to enter a corresponding recess, b, formed in the rear edge of the front-plate A. Such projection and recess are to duly centralize the two sashes,' or bring them into suitable positions for being locked. The front plate has two curved ribs or flanges, c d, elevated upon it, one being at its-front and In the front flange c, and at its middle, is a notch, c. There projects from the iiange c a horizontal dang-af, which is to operate with the hook g oi' the swinging catch O. This catch, arranged as shown, is so applied to the back plate B as to be capable of turning upon a standard or pivot, d', erected thereon, .suchv pivot at its junction with the catch or swinging lever C having flat faces h i, arranged as shown in Fig. 4.

The catch or swinginglever O is tubular, and carries a slidebolt,E, notched as shown at k, and projecting beyond the outer end of the catch, in manner as represented. A pin, l, going down through the catch, and a s1ot,m, in the bolt, serve .to keep the latter in the catch, against the pressure of a helical spring, c, arranged therein. This spring is dropped between the bolt and a slide, p, the latter being arranged within the catch, and against the pivot thereof. The spring performs two functions-that is, it presses the slide backward and the bolt forward. The catch has a projection, r, to rest upon the top of the curved ange d when the catch is locked to the flange c. The projection r and the flange d aid in sustaining the weight of the upper sash, and in preventing the catch and its hook from being bent out of their normal positions by the downward pressure of the said sash. A knob or' projection, s, erected on the catch or swinging lever, or arranged in it in manner as shown, serves as a rest for the foreinger ot' a persons hand, while with the thumb he may be pushing the bolt inward. It also answers as a handle, to facilitate the movements ofthe catch. On the catch or swinging lever being turned nearly back either way, the spring acting against thel slide, and forcing it against one of the flats h t', will cause the catch to be moved wholly back, and to be held in such position, in order that it may be out of the way of the lower sash, or not beinjured thereby, while the upper sash may be in the aet ot' being depressed, or the lower sash of being raised. On turning the catch or swinging lever around over the notch of the catch-plate the bolt will be shot into such notch, and'the two will serve to prevent the catch from being moved either way on its pivot.

I claim as my invention- The catch or swinging lever C, provided with the locking-bolt E, the slide 10, and the spring o, arranged between and applied to them, as shown, in combination with the pivot D, having the flats h i', and with the front plate A, provided with the notched iange c, all being constructed, arranged, and operated substantially as set forth.
